使用arcgis for android 10.2.x中加载离线地图，使用tpk + geodatabase模式：

1、初始化tpk文件

// 初始化离线切片
String yxtPath = Environment.getExternalStorageDirectory() + File.separator + "ArcGis" + File.separator + "yxt.tpk";
ArcGISLocalTiledLayer yxtLayer = new ArcGISLocalTiledLayer(yxtPath);
mMapView.addLayer(yxtLayer);

1、初始化geodatabase文件

// 离线地图geodatabase文件路径
String path = Environment.getExternalStorageDirectory() + File.separator + "ArcGis" + File.separator + "xxx.geodatabase";
Geodatabase localGdb = null;
try {
    localGdb = new Geodatabase(path);
} catch (Exception e) {
    e.printStackTrace();
}
if (localGdb != null) {
    for (GeodatabaseFeatureTable gdbFeatureTable : localGdb.getGeodatabaseTables()) {
        if (gdbFeatureTable.hasGeometry()) {
            FeatureLayer featureLayer = new FeatureLayer(gdbFeatureTable);
            mMapView.addLayer(featureLayer);
        }
    }
}
